Application filed June 5,1905. Serial No. 263,802.

To (ZZZ whom it may concern.-

Be it known that I, CHESTER E. SHULER, a citizen of the United States, residing at Clifton, in the county of Washington and State of Kansas, have invented certain new and useful Improvements in Sheet-Music-Leaf Turners, of which the following is a specification.

This invention has relation to sheet-musicleaf turners; and it consists in the novel construction and arrangement of its parts, as hereinafter shown and described.

The object of the invention is to provide a turner for sheet-music which may be attached to a piano, organ, or other musical instrument and which is so constructed that by depressing a button the leaves of the music may be turned successively in one direction and by depressing another button the said leaves may be turned successively in the opposite direction.

The turner is so constructed that it may be folded up and the parts slipped together, so

as to occupy but small space for transportation or when not in use.

In the accompanying drawings, Figure 1 is a front elevation of the music-leaf turner. Fig. 2 is an edge elevation of the same. Fig. 3 is a front elevation of the lower portion of the music leaf turner with parts removed. Fig. 4 is a horizontal sectional view of the music-leaf turner cut on the line 1 4: of Fig. 3. Fig. 5 is a transverse sectional view of the music-leaf turner cut on the line 5 5 of Fig. 1. Fig. 6 is a top plan view of the segments, showing one of the gear-wheels broken away. Fig. 7 is a top plan View of one of the lugs, showing one position of the springactuated pawl carried thereby. Fig. 8 is a top plan view of one of the lugs, showing another position of the spring-actuated pawl carried thereby. Fig. 9 is a top plan view of one of the arms, showing the spring bearing against the substantially triangular end thereof. Fig. 10 is a transverse sectional view of a modified form of amusic-leaf turner. Fig. 11 is a side elevation of a modified form of a lever for operatinga music-leaf turner. Fig. 12 is a top plan View of a modified form of the inner end of one of the turning-arms. Fig. 13 is a side elevation of the spring for holding the leaf-turning arms. Fig. 1 1 is a top plan view of the clasp for holding the middle of the sheet of music, and Fig. 15 is an edge view of one of the clasps for holding and turning the music-leaf.

The bar 1 forms the center of the rack for holding the sheet of music. To the said bar 1 are pivoted the horizontal bars 2 2, which extend on either side of the said bar 1. The outer ends of the said bars 2 2 on each side are connected by the vertical bar 8. By means of the set-screws 1 the bar 1 is adjustablysecured to the angle-iron 5, and by means of the set-screws 6 the said angle-iron 5 is adjustably secured to the angle iron 7. By means of the set-screws 8 the upright 9 is adjustably secured to the angle iron 7 The lug 10 is fixed to the said upright 9, and the lugs 11 and 12 are adapted to slide upon the upright 9. The screw 18 bears at its lower end against the lug 10 and is screw-threaded indicated in Fig. 2, and is provided with the jam-nuts 14 14c, which are adapted to engage the upper sides of the said lugs 11 and 12. The rearwardly-extending bars 15 and 16 are pivoted to the inner ends of the lugs 11 and 12, respectively, and the said bars 15 and 16 are provided with the oppositelydisposed pads 17 17. The set-screws 18 18 adjustably secure the bars 19 19 to the bars 15 and 16 and are provided at their inner ends with the oppositely-disposed pads 20 20. The said pads 17 17 and 20 20 are adapted to engage the framework of the piano or organ, (not shown,) and thereby hold the musicleaf turner in place upon the instrument. It is obvious that with the mechanism provided with the adjustments as above described the various parts may be so adjusted as to fit any style of framework of the instrument and that the music-leaf turner may be readily applied to or detached from the instrument. The said bar 1 is provided with the clasp 21. which is adapted to hold the middle of the sheet of music. Immediately below the said bar 1 is located a casing 22, in the center of which is vertically supported a shaft 23. The inner ends of the arms 24 24 are journaled upon the said shaft 23. The said arms are made in sections, the outer section of which may be adjusted longitudinally in or out, and the extreme outer ends of the said outer sections are provided with the clasps 25, which are adapted to receive thelower edges of the sheet of music. The major portions of said arms 24E are in vertical planes, but near their inner ends the said arms are twisted and the inner ends thereof are in horizontal planes. The said arms are provided upon thelr upper through perforations in the lugs 11 and 12, as.

edges with the lugs 26 and at their lower edges 1 and lug 32 takes place in an opposite direcwiththe lugs 27. The gear-wheel 28 is journaled upon the shaft 23 and is provided with a laterally-extending lug 29, which in turn is provided with a springactuated pawl 30, which is adapted to engage the lugs 27 of the arms 24 and to turn the same successively. The gear-wheel 31 is fixed to the shaft 23, and the laterally-extending lug 32 is also fixed to the said shaft 23. The lug 32 is provided with the spring-actuated pawl 33, which is adapted to engage the lugs 26 of the arms 24 and to turn the same successively. The hori zontal pin 34 is located below the shaft 23, and the levers 35 and 36 are fulcrumed upon the said pin 34. The inner end of the lever 35 is provided with a gear-faced segment 37, which engages the gear-wheel 28, and the lever 36 is provided at its inner end with a gear-faced segment 38, which engages the gear-wheel 31. The extensions 39 39 are pivoted to the forward end of the levers 35 and 36 and are provided with the buttons 40 40. The coil-springs 41 41 surround the pin 34. The ends of the said springs are secured to the lug 42, located within the casing 22, and the other end of one of the said springs 41 is attached to the segment 37, and the other end of the other said spring 41 is attached to the segment 38.

By reference to Figs. 7 and 8 an illustration of the method by which the spring-actuated pawl operates the leaf-turning arms may be seen. As the construction and operation of the spring-actuated pawl 33 are the same as that of the spring-actuated pawl 30, a description of one will answer for both. The said pawl is provided at one end with a swell 43, which is adapted to bear against the inner edges of the lugs 26 until it passes beyond the last lug, as shown in Fig. 8, when the spring actuating the said pawl forces the projection 44, which is located immediately behind the swell 43, against the edge of the face of the last lug 26 of the series. Then as the lug 32 is carried around the arm 24, to which the said last lug 26 of the said series is attached, is also carried around. Thus the sheet of music held by the clasp 25 of the said arm is turned. The arm 24 is positively operated through the one-hund red and eighty degrees of its movement by the pawl 33, attached to the lug 32. The n'iovement of the lug 32 is accomplished in the following manner: hen the extension 39 is depressed, the outer end of the lever is carried down and the segment 38 is made to describe a partial rotation, which causes the gearwheel 31 to turn, and the shaft 23 being fixed to the said gear-wheel 31 and also being fixed to the lug 32 carries the said lug around. Nhen the pressure has been relieved from the said lever 36, the spring41, attached thereto, causes the parts to assume their normal position. The operation above described for the segment 38, gear-wheel 31,

claim as new, and desire 5 tion. However, when the outer end of the lever 35 is depressed the lever 35 and its attachments are caused to assume their normal positions by its spring 41.

The lower end of the bar 1 is provided with the props 45, which are adapted to engage the face of the piano or organ and to hold the music-leaf turner out at the proper angle.

The casing 22 is provided in its front with a slot 46, through which the arms 24 extend, the lugs 26 and 27, however, being located within the said casing 22. By reference to Fig. 9 it will be seen that the inner ends of the arms 24 are made substantially triangular in shape, as at 47, and that the spring 48 is attached at one end to the casing 22 and bears atits other end against the edges of the angular portion 47 of the arms 24, and thus the said arms are held in position after they have been turned. By reference to Figs. 12 and 13 a modification of this construction is shown in which the corners of the angular portion 47 are provided with the rollers 49 and that the end of the spring 48 is slit into tongues 50, and each tongue is provided with the groove 51, which is adapted to receive the rollers 49 49 of the arms 24.

In the modified form shown in Fig. 10 the means forturning the arms 24 are substantially the same as that above described. The gear-wheels 28 and 31, however, are turneu by means of a rack 52, which is moved longitudinally by means of the bell-crank lever 53, pivoted at one end thereto and having a vertical rod 54 pivoted to the other ends thereof, with the button 55 attached to the lower end. The springs 56 are adapted to draw the parts into their normal positions.

In the form of the invention as illustrated in Fig. 11 the bell-crank lever 57 is pivoted at its upper end to the rack 52 and is provided at its other end with the button 58.

It will thus be seen that the parts may be easily and readily collapsed for convenience in shipping or packing, and, if desired, the bearings throughout the device may be in the form of ball, roller, or plane bearings, as convenience or faneymay require.
